FURNACE FOR THE HEATING AND UNWINDING F ITIRE.

Application filed March 26, 1925. serial No. 18,574.

T0 all whom t may concern:

Be it known that I, ANDR FLIX JACQUE- MiN, citizen of the Republic of France, residing at Saucourt, Haute-Marne, France, have invented certain new and useful Improvements in Furnaces for the'I-Ieating and Unwinding of Vire, of which the'following is a specification.

My invention relates to a furnace adapted for the heat-ing of iron wire or the like in the state of rolls, and for the unwinding of the same without cooling the wire to any appreciable degree.l 4 1 The said furnace comprises a chamber in which is mounted upon a pivot al device resembling a rotating drum or reel which is adapted to carry the roll of wire and whereof the central part constitutes the heating portieri of the furnace. This latter has a lateral aperture for the discharge of the wire in the highly heated state in order to supply the machines utilizing the wire accor-ding as the latter is unwoun-d from the said drum or reel.

Various particular arrangements may be optionally provided in order to. facilitate the operating of the furnace and 1n order to improve its working, as will be set forth 1n the following description relative to an e1n bodiment of the invention.

In the appended drawings:

Fig. l is an elevational section of the said furnace.

Fig. 2 is a sectional and plan View, ac-

V cording to the line II-II of Fig. 1.

In the said figures, the furnace properly so called comprises a chamber 3 which is lined with refractory material and is mounted on the upper part of a metallic frame 5; said chamber is closed by a cover 6 and contains a drum or reel of a refractory metal 7 which is disposed upon a disk 8 mounted at the end of the hollow shaft 9' which is supported at the bottom upon a ball bearing 10 secured to the main frame.

The central circular part of the drum 7 constitutes the heating portion of the said furnace, and comprises to this effect a grate. 11. Upon the periphery of the said drum is provided an annular flange or support 12 supporting the roll of wire 13 to be heated. Suitable apertures 14 are pro-vided around the chamber 3 for the discharge of the products of combustion, and in the interior of the furnace an annular wall 15 is disposed above the said apertures, forming` a baflie. Between the bottom 16 of the chamber 3 and the disk S is provided a hydraulic joint 17 supplied with water by a special conduit 18. The chamber 3 comprises an aperture communicating with a channel 19 for the discharge of the wire. I may further provide a sight hole 2O closed by a sliding door 21 for the periodical observation of the' functionmg.

In the disk 8 are formed apertures 22 for the passage of the air for the combustion which is admitted. below the grate 11 and enters the furnace through the door 23. In its central region the disk 8 forms a basin communicating at the bottom with a` conduit 25 formed at the centre of the vertical shaft 9, said conduit being connected through the stufiing box 26 with a water pipe 27. To the shaft 9 is keyed the bevel gear 28 co-operating with a like gear 29 mounted upon a rod 30 which is slidable lengthwise in the bearings 31, 32 of the main frame and has at the end a hand wheel 33. The'operation of the said furnace is as follows:

The cover 6 of the furnace is removed, and a roll of Wire 13 is placed upon the drum 7 and 1s laid upon the ianged part 12. Fuel 1s disposed in the grate 11 and lighted, and the said cover is then put in place; air is admitted through the aperture 23 while a certain quantity of water which is delivered through the conduit 25 and fills the basin 241 wherein it evaporates. The mixture of air and water which enters the heating portion through the grate 11 will further the combustion and produces flames which impinge upon the roll of wire 13, passing between the flanged part 12 and the baffle 15 and issuing from the furnace through the apertures 14.

In this manner the said roll of wire becomes rapidly heated, and its temperature may be readily observed by opening the door 21 and examining the said roll while turning the hand Wheel 33 in order to rotate the hollow shaft 9 and the drum 7 When it is considered that the wire has been brought to a sufficient temperature, it is seized by the outer end and drawn through the aperture 19; it is simply necessary to bring this end of the wire to the machines utilizing the saine which may be mounted as close to furnace as desired, and which may be supplied in a Continuous manner as the wire is unwound iiroin tlie drinn 7. lit is obvious that during its unu'inding, tiie wire will not be cooled to any appreciable degree7 and it may thus be treated in the moet favourable conditions ot temperature.

The iurnaee according to my said invention is adapted it'or use in a considerable ninnber of industries. For example it provides for tile eontinuoml feeding' oi' bolt making niaeliines; in ille known methods` suoli niaeliines are periodieally supplied with abort lengths of wire wliieli beeouie rapidly cooled and are dillieult to handle.

The annealing' lurnaee providery for the utilization olf the waste u'iro troni the rolling niille. Het rolling; can al 'aye be employed with a reduced uuniber oi opera tions for sinall section iron bars, niouldings= and especiallyv thin hoop iron (0.5 inni.) Wliioli Could not be rolled hot by the known methods; suoli products uere treated in the cold state and had to be put Yrequentb7 through tlie rolle, with .frequent annealing in the meantime.

The utilization ot' the nfurnace according to niy Said invention is not liniited to the above-mentioned examples, and the said fur nace is adapted ior a wide. range ot' uses. The 'furnace itsel't is susceptible of all Suitable niodilieaiions in detail according to eaell particular ease, without departing lroin the principle ol the invention.

I elaiin:

A 'iiurnaee for heating wires, eonipriising a elianiber in u'liieli a Sort o't revolubie druinlike element in mounted upon a pivot; Said drum-like eleinent carriers iiie wire, and iis central part constitutes the heating portion ol the furnace, :i lateral aperture being pro vided in the Said elianiber l'or the disrliarge oi the Wire as it is uni-oiled troni the dru1nlike element.

In testimony n'liereo'l l have hereunto set my hand.

ANDR FELIX JACQUEMIN.
